I have to disagree, the Casios speaker phone is the loudest and clearest Ive ever had, anyone ive talked to on it didnt even know they were on speaker. the ear piece is just as clear to me and loud as needed in a car even with radion on in the background. As far as keyboard goes the casio is much easier to use, takes less effort to push its rubber keypad. And if you inspect the ports on the Barrage, theres no gaskets to seal out water on say the charge port! where the casio has actual gaskets on everything that opens.
The battery on the Casio Rock lasts for a couple days literally with heavy use as well.
